Ice-making System Cleaning

Caution:
• Many ice machine cleaners contain acids.
• DO NOT use or mix with any other solvent-based cleaner products.
• Use rubber gloves to protect your hands.
• Carefully read all safety instructions printed on the container of the ice machine cleaner.
• Discard the first batch of ice produced after cleaning
Minerals that are removed from water during the freezing cycle will eventually form a hard scaly
deposit in the water system. Cleaning the system regularly helps remove the mineral scale buildup.
How often you need to clean the system depends upon how hard your water is or how effective your
filtration may be. With hard water of 15 to 20 grains/gallon (4 to 5 grains/liter), you may need to
clean the system as often as every 6 months.
1. Make sure that all the ice is off of the evaporator. If ice is being made, wait for cycle completion,
then turn the machine "OFF" at the ICE/OFF/WASH selector switch.
2. Remove all ice from the storage bin.
3. Keep the ice maker connected to the water supply, Pour 200 g of Nickel-Safe Ice Maker Cleaner
Solution into the water trough. After about 5 minutes, initiate the wash cycle at the
ICE/OFF/WASH selector switch by placing the switch in the "WASH" position. The machine will
run the Automatic Clean Mode.
4. Allow 30 minutes for proper cleaning. After cleaning, turn the machine "OFF" at the
ICE/OFF/WASH selector switch. Drain off the waste water to some container by drain pipe in the
left of the water trough.
5. Repeat steps 3 and 4 (without Ice Maker Cleaning Solution) to rinse the ice making system 3
times.
▪ Note: The use of the Ice Maker Cleaner Solution in the water bin during the rinse is not
needed.
6. Prepare a sanitizing solution made of a mild detergent and hot water (95º F to 115º F). Wipe the
entire bin inside and out.
7. Fill a spray bottle with the sanitizing solution and spray all corners and edges, making sure to
cover all surfaces with the solution.
8. Allow the solution to be in contact for at least 3 minutes, then dry all surfaces.
9. Repeat step 5 to rinse the ice making system one more time.
10. Place the ICE/OFF/WASH selector switch to the "ICE" position. The machine will return to the
regular ice making mode. Discard the first batch of ice.
